Compatibility depends on the engine model and manufacturer specifications. RC12YC may cross-reference with several other part numbers, but cross-references do not guarantee compatibility with every application.
Before ordering, compare the existing spark-plug number or consult the equipment owner’s manual. Check and adjust the electrode gap to the engine manufacturer’s specified measurement before installation; do not assume the plugs are correctly gapped for every application. Install and tighten according to the manufacturer’s procedures.
